Features• Variable axial piston double pump design for the open circuit.

• Various controllers available: hydraulic and electrical control

design available, which can combined the different controllers

of flow control, pressure control and power control.

• High working pressure ( 380 bar ) and long lifetime

• High efficiency, excellent self-priming performance

• 1 inlet and 2 outlets

• Special pump housing structure design meets the low noise

requirements.

• More suitable for mobile machinery like excavators, cranes,

drilling rigs and so on.

·E1 Electro-proportional displacement control principle

Electro-proportional displacement control: With pilot-pressure-related control, the pump displacement is adjusted in proportion to the pilot pressure. Basic position without pilot signal is Vg min, which includes the mechanically depressurized basic position Vgmin. With increasing pilot pressure the pump swivels to a larger displacement. The necessary control power is taken from the operating pressure or the external control pressure applied to port P. If the pump is to be adjusted from the zero basic setting or from a low operating pressure, port P must be supplied with an external control pressure of at least 30 bar, maximum 50 bar.
